There is also shown in Fig. 4 an outer mask I9 substantially coniform in shape and arranged to overlie the inner periphery of the tire-carrying rim so as to protect the same during the striping operation. A central holding ring 20 generally annular in form and at its lower edge provided with a plurality of slots 2|, such ring assisting in holding the inner edge of the mask I3a snugly in engagement with the face of the wheel and also- 10 assists in preventing the paint used during the striping operation from spotting the inner periphery of the wheel. accommodate the bridging members I50, in the manner illustrated in Fig. 4.

An operating switch (not shown) is provided for the electro-magnetic coils 8 and 8a in order that the same may be intermittently energized by the operator during the desired periods of time. Preferably, such a switch will be a foot switch mounted on the floor. The method of operation of the above-described apparatus is as follows:

The operator places the wheel to be striped on the top of the rotatable plate 5 or 5a substantiallyin the position as shown in Figs. 1 and 4. The shield I3 or I3a is then placed over the wheel. The magnetic coil 8 or 8a is next energized, and the magnetic flux thereof will tend to not only hold the wheel on the top of the plate 5 or 5a,

but will also tightly clamp the shield I3 or l3a down against the surface of the wheel. The operator next applies the striping material over the aperture I4 or Ma by means of spraying or painting or any other conventional method, and

at the same time the wheel and plate 5 or 5a may be rotated so that it is unnecessary for the operator to change his position.

It is of utmost importance in the operation of applying a stripe or other ornamentation to a surface that the mask or shield be at all times tightly clamped thereagainst in order to prevent the applied material from running under the edges of the shield. It will thus be seen that the above-described method and means substantially eliminates any such hazard and that the wheel and shield during the striping operation are at all The slots 2I are provided totimes firmly held in position without necessitating the presence of clamps or similar fastening devices. The mere operation of an electric switch accomplishes the function of releasing and clamping the assembled elements.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the means and the steps herein disclosed, provided those stated by any of the following claims or their equivalent be employed.

I therefore particularly point out and distinctly claim as my invention:

1. In an apparatus for applying designs to magnetic metallic articles by means of a stencil, the combination of a supporting standard, a plate rotatably mounted on said standard for carrying such article, a stencil composed of a magnetic material and adapted to overlie the surface on which the design is to be placed, and an electromagnet so mounted with respectv to. said plate that the lines of flux of the electro-magnet will pass through said plate, through such an article placed thereon, and through said stencil placed upon such article.

2. An apparatus for supporting a stencil of magnetic material, upon a wheel formed of magnetic material, while applying a design, therethrough to the surface of such wheel, comprising a supporting standard, a magnetic plate rotatably mounted thereon, and means magnetizing and demagnetizing said plate at the will of an operator.

3. In an apparatus for applying a design by stencil, a supporting standard; a plate of magnetic material rotatably mounted thereon; an article to be decorated placed upon said plate, said article being substantially of magnetic material; a stencil'of metallic material placed upon said article; and means magnetizing and demagnetizing said rotatable plate at the will of an operator whereby lines of magnetic force pass through said plate, said article and said stencil holding same in fixed intimate contact.
